They reveal that the chemical composition of the deep mantle has remained almost intact since the Earth's formation 4.5 ...

The vertical movement of the mantle is one of the driving forces that brings about large-scale geological changes to the ...

Scientists have made significant progress in drilling into the Earth’s crust, reaching unprecedented depths that bring them ...

Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents ...

Scientists found a rhythmic mantle plume beneath Ethiopia is slowly tearing Africa apart - hinting at the birth of a new ...

Geophysicists have long theorized that the mantle transition zone, wedged between the upper and lower mantle at depths of 410 to 660 kilometers, could be a secret vault for Earth’s lost water.

A new analysis of rocks thought to be at least 2.5 billion years old by researchers at the Smithsonian’s National Museum of Natural History helps clarify the chemical history of Earth’s mantle—the ...

That part of the mantle is made of old tectonic plates that break into tiny pieces when they sink deep enough into the planet. The LLSVPs, by contrast, contain larger crystals than their surroundings.

A new way of measuring structures deep inside Earth has highlighted numerous previously unknown blobs within our planet's mantle. These anomalies are surprisingly similar to sunken chunks of Earth ...

Geologists Uncover Remnants of Earth’s Mantle That Have Lasted Over 2.5 Billion Years New research suggests that a discrepancy in rocks shows they endured extreme heat, and reveals more about an ...

In contrast, the mantle, which lies between the planet’s outer crust and the molten core, is 1,800 miles (2,897 kilometers) of mostly solid rock.
